Worried

So I'm starting to get a bit worried about my blood pressure. I have had high blood pressure for a couple of years now and for the most part, it has been very well controlled on medication. When I saw my OB/Gyn in September she said she wasn't worried about it since it was well controlled, at that time it was running about 115/70 which was great. But I was taking an ACE inhibitor which isn't allowed for pregnancy. So I switched to Labatelol which is a beta blocker and it isn't working as well. I've been running about 130-150 over about 80 for the last couple of months and finally went to my doctor (not OB/Gyn) last week to see about adjusting. I know that beta blockers are the preferred med for pregnant women but I also know that they do Procardia sometimes also. He didn't really want to prescribe the procardia and he upped my dose of my current med during the day time. However it still isn't going down. I am still at the same level I was before I increased my med. It is frustrating as I know that I need this under control before I get pregnant. I'm trying not to eat much salt and trying to eat good in general. I also am working on (recently) getting better about exercising so hopefully it will go down in a week or two. I guess if that doesn't work, I will try to call the OB doc and see what she thinks I should do. I know that stressing about it won't help to lower it either. It's just frustrating me like crazy. Sometimes I hate my body and how it won't cooperate.
